The Active Ingredient Is: Caffeine (Natural Source)

Caffeine is a natural stimulant that helps promote mental alertness and can support exercise performance. This form is derived from natural caffeine sources and is included to provide a quick, energising effect.

This formulation uses a natural caffeine source to contribute to the product’s profile of focus and energy before activity.

What Does Caffeine Do?

Caffeine can support heightened alertness and energy levels during activity, which may help with reaction time and perceived effort. This aligns with guidance on normal function of the central nervous system and energy metabolism.

Dr. Davis of Harvard University found that caffeine can enhance endurance and alertness in adults, supporting its role in normal energy production and performance during physical activity.
